THE RIVER DRYING CONCEPT: A NEW ECOHYDROLOGICAL PERSPECTIVE AND CONCEPTUAL MODEL FOR STREAM NETWORKS OF THE ANTHROPOCENE
Almost every stream conceptual framework or model used today has arisen from synthesizing studies of perennial streams. And yet intermittent rivers and ephemeral streams represent ~50% of global stream length and are becoming more prevalent in many areas. We now know that virtually every stream network will experience flow cessation and/or drying at some point in space or time. We also now know that the hydrology, biogeochemistry, and biodiversity of intermittent and ephemeral streams and rivers are often very different from perennial ones, challenging some of the central assumptions of previous stream conceptual frameworks and models. This calls for a paradigm shift to one that explicitly acknowledges the role of flow cessation and drying in governing the structure and function of stream networks. Here we review existing stream conceptual frameworks and models. We use this rich history to extend previous tenets of stream conceptual frameworks and models to a new ecohydrological perspective and conceptual model for stream networks, one that includes flow cessation and drying as primary drivers of stream ecosystem structure, functions, and services in a human-dominated epoch.
